Embodiment Construction

[0043] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0044] Firstly, an example of the TDS detection system provided in this specific implementation manner is introduced.

[0045] figure 2 is a block diagram of a TDS detection system according to an embodiment of the present invention, such as figure 2 As shown, the TDS detection system includes a temperature detector 10 , a TDS detection circuit 30 and a processor 50 .

[0046]When the test system is applied to products such as water purifiers, the temperature detector 10 detects the temperature of the measured water in real time. Preferably, the temperature detector 10 is a temperature-sensitive package, and the temperature-sensitive package is arranged in the water tank of the water purifi...

Abstract

The invention discloses a TDS (total dissolved solids) detection method, device and system. The detection method comprises the following steps: detecting the temperature of water to be detected; acquiring a water quality sampling value of a water quality probe in the water to be detected; determining TDS of the water to be detected according to the temperature and the water quality sampling value of the water to be detected. According to the detection method, the temperature of the water to be detected is used as a condition for determining the TDS in the water, so that the influence of water temperature to the TDS accuracy can be overcome, and the accuracy of the TDS detection for the water quality can be improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a TDS detection method, detection device and detection system. Background technique [0002] Total Dissolved Solids (TDS, Total Dissolved Solids) refers to the total amount of solids dissolved in water. The measurement unit is parts per millions or mg / Lmilligram / Liter. The physical meaning is how many milligrams of total dissolved solids are dissolved in 1 liter of water. In layman's terms, the TDS value represents the impurity content of dissolved substances in water. The larger the TDS value, the greater the impurity content in the water and the poor water quality. On the contrary, the lower the impurity content, the better the water quality. [0003] At present, most of the water quality TDS detection methods use DC voltage to drive the water quality probe to obtain the water quality sampling value, and then directly obtain the water quality TDS according to the sampling value-T...
